+## Queueing Commands
+
+Spock automatically queues commands to run in the background when you have a queue driver set.  This can be helpful if you have git set to automatically push, or if you are running any commands that take time to execute, causing your users to experience wait time.  To setup a queue in your statamic app:
+
+1. Ensure [Redis](https://redis.io/) is installed and running on your server.
+2. Add `QUEUE_DRIVER=redis` to your `.env` file. [What’s an .env file?](https://docs.statamic.com/environments)
+3. Run `php please queue:listen`.
